It seems like you may have mistakenly inferred that I have issues with the AUR?

I don't; I use Arch on 100% of my personal servers, have done so for something approaching 20 years, and don't see myself changing.

But I treat the AUR for what it is: a place where anybody can say "here's a PKGBUILD for folks" and it's on me to evaluate it on its merits.

I was legitimately asking the person upthread what other distro they felt had a better model for this kind of sharing, because they seemed to think this was a reason for Arch users to jump ship and I was curious what they thought would be the elements of a better system.
